Drop UDP packet by lenght

Postby red5goahead » Wed May 31, 2017 8:03 am

According to this post about these HDMI sender with HDbitT protocol (LENKENG , ESYNic ecc.)

https://blog.danman.eu/new-version-of-l ... /#comments

there is a problem with FFMpeg.

The HDMI sender broadcast an UDP multicast MPEG-TS stream that can used with vlc but it doesn't work with ffmpeg that can't recognize the stream.

(I solved the problem using VLC as a UDP-HTTP proxy, with http ffmpeg work fine)

[mpegts @ 029c2b00] probed stream 1 failed
[mpegts @ 029c2b00] Could not find codec parameters for stream 1 (Unknown: none): unknown codec
Consider increasing the value for the ‘analyzeduration’ and ‘probesize’ options

An issue is this stream contain a lots of UDP zero lenght packet .

It would be fine if FFMPEG could avoid these packets. In Windows desktop system, firewall don't allow to drop them out.
